Quadrilateral mesh simplification
We introduce a simplification algorithm for meshes composed of quadrilateral elements. It is reminiscent of edge-collapse based methods for triangle meshes, but takes a novel appr...

Quadrilateral Meshing with Anisotropy and Directionality Control via Close Packing of Rectangular Cells
A new technique for automatically generating anisotropic quadrilateral meshes is presented in this paper. The inputs are (1) a 2D geometric domain and (2) a desired anisotropy

Quadrilateral meshes with bounded minimum angle
In this paper, we present an algorithm that utilizes a quadtree data structure to construct a strictly convex quadrilateral mesh for a simple polygonal region in which no newly cr...

Small Strictly Convex Quadrilateral Meshes of Point Sets
In this paper we give upper and lower bounds on the number of Steiner points required to construct a strictly convex quadrilateral mesh for a planar point set. In particular, we sh...

Quadrilateral Remeshing
The use of polygonal meshes, especially triangle meshes, is manifold but a lot of algorithms require the mesh to be structured in a certain way and cannot be applied to an arbitra...
